SeleIn China's later Han era, there lived a politician called Yang Zhen, a man known for his upright character. After Yang Zhen was made a provincial governor, one of his earlier patrons, Wang Mi, paid him an unexpected visit. As they talked over old times, Wang Mi brought out a large gold cup and presented it to Yang Zhen. Yang Zhen refused to accept it, but Wang Mi persisted, saying, “There's no one here tonight but you and me, so no one will know.” “You say that no one will know,” Yang Zhen replied, “but that is not true. Heaven will know, and you and I will know too.” Wang Mi was ashamed, and backed down. Subsequently Yang Zhen's integrity won increasing recognition, and he rose to a high post in the central government.
